The Diocese of Sheffield is an administrative division of the Church of England, part of the Province of York.
The Diocese of Sheffield was formed 23 January 1914, by the division from the Diocese of York (along with that part of the Diocese of Southwell in the city of Sheffield). It covers most of the County of South Yorkshire (except Barnsley), with a small part of the East Riding of Yorkshire, one parish in North Yorkshire and one in North Lincolnshire – an area of almost 576 square miles (1,490 km2). It is headed by the Bishop of Sheffield and its Cathedral is Sheffield Cathedral. The diocese is linked with the Diocese of Argentina. Since 1990 it has been linked with the Evangelical Church in Germany's Hattingen-Witten District in Westphalia.
The Diocese is subdivided into 12 deaneries, split between two archdeaconries:
- Archdeaconry of Sheffield and Rotherham (originally Archdeaconry of Sheffield)  (Archdeacon: Malcolm Chamberlain)
- Archdeaconry of Doncaster (Archdeacon: Steve Wilcockson) 
- Snaith & Hatfield
- West Doncaster
